VAPOR-BURNER.

SPEGIF ICATION formingpart of Letters Patent No. 269,834, dated January 2, 1883,

' Application filed January 11, 1882. (No model.)

To all whom it may concern:

Be it known that I,ZEBULON DAVlS, of Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Vapor Burners; and [do hereby declare the following to be a lull, clear, and exnot description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention consists in the combination of a combustion-chamber, a pivoted laterallymoving cover, and a laterally-movable induction-tube and lever, the cover and the induction-tube being moved by the lever in such a manner that the cover will, move about twice the distance moved by the induction-tube.

It further consists in the combination of a combustion-chamber, a laterally-movable top or cover, a laterally-movable induction-tube, and a lever by which the two.parts are moved, so that one part moves about twice as far as the other.

The object of my invention is to produce a vapor-burner in which the flame can be kept burning after it has been turned down, and thus enable the parts not only to be kept sufficiently hot to keep the fluid vaporized, but to enable a full flame to be turned up at any moment, whereby the burner is always kept ready for instant use.

Figures 1 and 2 are side elevations of my invention, taken from different sides. Fig. 3 is a plan view; and Fig. 4 is an inverted view of the burner, thepipe H and its attachments being removed, so as to more perfectly show the movement of the different parts. Fig. 5 is an inverted view of the burner complete.

Arepresents thecom bustion-chamber, which may be of any shape, size, or construction that may be preferred. This chamber may be cast in a single piece with the base, or the base may be made in a separate piece by itself. Instead of forming the top of the chamber in one solid piece with the chamber, or having it made verticallyadjustable by means ofa screw, the top 0 is here fastened upon a rod which extends upward from a lug or projection which is formed upon the bottom of the combustion-chamber, so that the top can be swung freely around to one side, and thus leave the top of the chamber entirely open, for the double purpose of cleaniugthe chamber out, when so desired, and for the purpose of allowing the flame to continue burning in the chamber after the vapor has been shut off. When this pivoted top or cover 0 is moved to one side, so as to leave the top of the chamber entirely open, the vapor can be turned down and sufficient air admitted into the combustion-chamber to prevent an explosion, and thus extinguish the flame. Where the cover is moved to one side the air enters freely at the same time that the vapor is escaping upward, and the flame can be turned down to any desired degree without having the flame extinguished. The rod B, to which the cover 0 is fastened, passes down through the lug or projection on one side of the bottom of the combustion-chambcr, and to this rod is fastened the curved lever D, as shown in Fig. 4. It being intended that the cover 0 shall move about twice the distance that the pivoted tube E shall move, the lever D is so shaped that it moves the cover 0 the proper distance before the arm or branch F of the lever strike-s against the side of the inlet-tube E, which is pivoted to the under side of the combustionchamber. This pivoted inlet-tube is intended to move laterally about one-half of its diameter, so that the flame which rises from the point of the needle G will be divided by the lower end of the tube, and thus cause a portion of the flame to pass up into the combustion-chamber, while the other portion plays up along the outer side of the inlet-tube and against the bottom of the combustion-chamber, so as to keep the parts sufficiently hot to keep the fluid which passes in through the tube H always vaporized. While the inlet-tube E and the coverO are moved to one side the flame shoots freely up into the combustion-chamber to any desired height, andwill continue burning without the slightest danger of it being accidentally extinguished, and thus at any moment, when it is desired to use the burner again, it is only necessary to move the lever D in such amanner as to bring the inlet-tube E and cover 0 into their proper position, when the whole 7 flame can be turned up to its full height and the burneris ready for immediate use. On the bottom of the combustion-chamber will be be attached to the lever can be used for this formed a suitable stop, 0, which will prevent the tube from being moved too far. The cover 0 is so adjusted that it will remain just sufficiently far above the top of the combustionchamber to form a narrow slot through which the proper flame will be exposed; or it may be allowed to rest solidly upon the top of the chamber, and then holes be drilled through the top in the usual manner. This top is here shown as connected to the operating-lever, which in its movement strikes against the inlet-tube, so as to cause the two parts to move together; but, if so preferred, the twoparts may be entirely disconnected, and the top 0 may be made to move laterally without having the inlet-tube E made removable. It is generally desirable that some object or device should be moved directly over the flame, so that the fl'ame will impinge against it, so as to retard or prevent its tendency to burn away from the needie-point and be extinguished; but it is not necessary that the inlet-tube should be used. for this purpose. Any otherdevice which may purpose. So long as thecover G can be swung back out of the way the flame will burn up 5 through theburner withoutbeing extinguished. i

l'laving thus described my invention, I claim- 1. In a vapor-burner, the combination of a combustion-chamber with a pivoted cover, a pivoted inlet-tube, and a lever for moving the two parts, substantially as described.

2. In a \ill'lOP-btllilfil, the combination of a combustionchamber with a movable inlettube which can be adjusted in relation to the opening in the bottom of the chamber and the flame or exit of the gas, so that the flame will impinge against its sideor sides, substantially as set forth.

3. The combination of the combustionchamber provided with the pivoted cover U, the lever D, a rod to which the cover andlever are fastened, and the pivoted inlet-tube E, the lever D being so formed as to move one of the parts farther than the other, substantially as described.

In testimony whereof I affix mysignature in presence of two witnesses.
